Hi team,

We are getting an error logs like below. Anyone has idea on this why its coming.

24.08.2023 09:32:37.387 *ERROR* POST /content/dam/dam:batch.metadata.json HTTP/1.1] org.apache.sling.servlets.post.impl.operations.ModifyOperation Exception during response processing. org.apache.sling.api.resource.PersistenceException: Unable to create node at /content/dam/dam:batch.metadata.json at org.apache.sling.jcr.resource.internal.helper.jcr.JcrResourceProvider.create(JcrResourceProvider.java:480) [org.apache.sling.jcr.resource:3.0.18] ... 160 lines omitted ... at java.lang.Thread.run(Thread.java:748) Caused by: javax.jcr.nodetype.ConstraintViolationException: No default node type available for /content/dam/dam:batch.metadata.json

Hi,

This error typically occurs when the node being created does not match the expected node type for that location in the JCR.

Check Node Type: Review the node type definition and requirements for the location "/content/dam/dam:batch.metadata.json." Make sure that you are attempting to create a node that complies with the expected node type.

Node Name Format: Ensure that the node name you are using (in this case, "dam:batch.metadata.json") adheres to the naming conventions and restrictions defined by the node type. It should not contain any invalid characters or reserved words.

Check for Resource Existence: Before attempting to create a new node, verify that a node with the same path does not already exist. If it does exist, you may need to modify the existing node instead of creating a new one.

Permissions: Ensure that the user or service account attempting to create the node has the necessary permissions to perform this operation. Lack of permissions can also result in ConstraintViolationExceptions.
